A failing file:sendfile call would often send a message
{inet_reply, Port, {error, Reason}} that would pollute the mailbox
of the calling process.
TCP_REQ_SENDFILE has its own reply messages format
{sendfile, _, _} and does not expect an inet_reply message.
Solution: Suppress inet_reply error message if TCP_ADDF_SENDFILE
is set.
|
|
driver_select() was called after port had been killed
by tcp_inet_sendfile() calling tcp_send_error().

While the system will keep working, the aux work will never run
and the affected scheduler never goes to sleep. OTP-15446 is a
good example of this.
As this error easily flies under the radar it's best to make it
immediately visible. The assertions we had in debug builds were
clearly not enough to catch all sources of this problem.

erts: fix attempt to start timer when executing on dirty scheduler
OTP-15446

Since OTP R20, there is a possibility for MAJOR garbage collection to
run on dirty scheduler. So DistEntry destructor is being called on
dirty scheduler as well. This, in turn, leads to an attempt to schedule
timer on a dirty scheduler too, which is impossible (and will assert
on debug build, but does succeed for release build, creating an
infinite busy loop, since aux work wakes scheduler up, but dirty
scheduler cannot execute aus work).
There is a similar method in erl_hl_timer, see erts_start_timer_callback.

We only do this when the user has explicitly told us it's okay to
partially disable mitigation (spectre-mitigation=incomplete). The
macro is inert if it isn't.
|
|
Note that the ERTS_NO_RETPOLINE macro introduced by this commit is
completely inert unless spectre-mitigation is set to 'incomplete.'
This includes when mitigation has been manually enabled through
CFLAGS, so it should be impossible for it to unintentionally
disable mitigation.

Also fix erts_debug:get_internal_status(node_and_dist_references)
for catree to also search route node keys for offheap stuff.
|
|
to be usable by other application tests.
|
|
with some code moving and removed obsolete comments.
